The wife and I always ran 87 to 89 octane in our 2009 Hardtop (non Turbo), I told her the other day that "WE MUST USE 92 or 93 octane in our new Mini S because the Turbo needs it". She got upset at the Xtra money we would have to spend.

If you punch out the numbers real quick it's only about $2.30 to $2.50 more for a full tank @ 12.4 gallons. 92 octane the other day was $3.54.

Perhaps it would have gone down better if you had said I WILL FILL IT UP for you dear when it needs doing you never need to bother, so the correct fuel is used?

I always use the top quality brand and highest octane I can get, does it make any difference to the car? nope! cant notice a darn thing, but it makes you feel better knowing youre doing the right thing.
